Answer:
The initial height of the base ball based on the equation for the height of the base ball,
is 3 ft
Step-by-step explanation:
For clarity, if we put the equation of the height of the base ball as
![h = -16t^2 + 32t + 3](https://tex.z-dn.net/?f=h%20%3D%20-16t%5E2%20%2B%2032t%20%2B%203)
Then the initial height of the base ball will be at the point t = 0
That is
or
h = 3 ft
The initial height of the base ball based on the equation for the height of the base ball,
is then = 3 ft.
Answer:
4 by 10
Step-by-step explanation:
4 times 10 is 40 (length times width)
4+4+10+20=28
Circumference = (pi) x (diameter) = 30 pi inches.
1 foot = 12 inches
1 mile = 5,280 feet = 63,360 inches
Number of revolutions in 1 mile = (63,360) / (30 pi) = <u>672.27...</u> revs (rounded)
Answer: 8.8
Step-by-step explanation:
Because
by the reflexive property, we know that
by AA.
So, by the triangle proportionality theorem,
![\frac{x}{5.3}=\frac{11.1}{6.7}\\x=(11.1/6.7)(5.3) \approx \boxed{8.8}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B5.3%7D%3D%5Cfrac%7B11.1%7D%7B6.7%7D%5C%5Cx%3D%2811.1%2F6.7%29%285.3%29%20%5Capprox%20%5Cboxed%7B8.8%7D)
